A tamper-proof bolt-seal incorporating a unique identification tamper detection sensor that cannot be restored or duplicated after the bolt. The sensor employs a resistive sensor wire embedded in the bolt. The resistive sensor wire has a randomized length to enable a unique resistive value for that sensor. The resistive value of the sensor is combined with an electronic identification code to create the unique seal identification for the tamper detection sensor, therefore giving the bolt a seal identification that is unique and that cannot be restored or duplicated.
